The main proteins involved are myosin, actin, and titin. Myosin and actin are the contractile proteins …
The myosin heads form cross bridges with the actin myofilaments; this is where they carry out a 'rowing' action along the actin. When the muscle fibre is relaxed (before contraction), the myosin head has ADP and phosphate bound to it. When a nerve impulse arrives, Ca ions cause troponin to change shape; this moves the troponin + tropomyosin complex away, leaving the myosin binding s… milestm reviewsWebnoun Any of the ultramicroscopic filaments, made up of actin and myosin, that are the structural units of a myofibril.
